I fail to see the complexity, but that's me.  In particular, the first
alternative (to have it disabled in certain locales) seems very simple
to me.

I've asked these questions a lot in this discussion, and still the
majority thinks that the locale in which Emacs is started should be
used for the defaults.  So you are in fact arguing with what the
majority says, not with me.

Do we have a clear definition of what are the criteria for this
feature to be "ready for prime-time as a default"?  You are in effect
saying that we will never be able to find good answers for those
questions.  We shouldn't be dismissing a good feature such as this
one, which many users like, due to FUD-like arguments.
